Dear friends,
Here is a technical question on a problem that is driving us crazy.

We want to play sounds from Matlab through an RME
Fireface 400 sound card. The problem is that when
we play a "silence" interval (array of zeros) we
can hear (and even record) a clear transient at
the onset of the _silence_ signal. We would very
much like to get rid of that onset transient. Any
cues as to how to get rid of it?
